Grandia 3 is a PS2 game made by those guys down at Game Arts in 2005. It's pretty overlooked for an RPG and a lot of people thought it's wasn't that great compared to others but we still like it nonetheless. It's colorful, it's charming, it's got some neat characters, a pretty neat story even if they didn't know all what to do with it and a unique battle system. I find it unique in that it focuses not only on the main combat (dealing damage, healing) but also on a meta-battle of gauge management where you try to deny the enemies as many turns as possible. It's also got a cool battlefield mechanic where positioning will affect what enemies get hit by attacks, kind of like in Chrono Trigger (protip, hang around the edges and use moves with a wide fan-pattern).
